Double-Barrel Action (December 7, 2012)

The Sun blasted out two coronal mass ejections (CMEs) in quick succession over a 12-hour period (Dec. 2, 2012). The
events are presented here by three of STEREO's (Ahead) instruments composited together. The Sun itself (shown in
orangish-red) is seen in extreme UV light; the inner corona (green) by the COR1 coronagraph; and the larger coronal area
by the COR2 coronagraph. The CME particle clouds were directed away from Earth.

SOHO began its Weekly Pick some time after
sending a weekly image or video clip to the American Museum of Natural
History (Rose Center) in New York City. There, the SOHO Weekly Pick is
displayed with some annotations on a large plasma display.

If your institution would also like to receive the same Weekly Pick from us
for display (usually in Photoshop or QuickTime format), please send
your inquiry to steele.hill@gsfc.nasa.gov.
